KLINGSPOR self-adhesive sanding disc PS 33 BK / PS 33 CK 150 mm grit 40 pack 100 (MPN 147647)

KLINGSPOR self-adhesive sanding disc PS 33 BK / PS 33 CK, 150 mm diameter, grit 40, pack of 100 is designed for coarse material removal and initial shaping on wood, painted surfaces, fillers and soft metals. The discs feature a durable abrasive mineral and a pressure-sensitive adhesive backing that allows fast attachment to compatible sanding pad or platen. Intended for orbital sanders and backing pad use, these discs provide consistent cutting performance for surface preparation and coarse sanding operations.

Advantages

The abrasive grain structure and resilient backing deliver aggressive stock removal while maintaining disc stability during operation. The self-adhesive backing ensures quick replacement and secure adhesion under typical orbital sanding conditions. Available in a large pack of 100, the discs reduce downtime for frequent disc changes and are suitable for workshop and production environments requiring repeated coarse sanding tasks.

Suitable for

• Coarse sanding and material removal on timber and panel products
• Preparing painted surfaces and removing old coatings
• Shaping and sanding filler and putty
• Sanding soft metals and non-ferrous alloys for deburring and contouring
• Use with orbital sanders, backing pads and sanding platens

Key specifications

• Diameter: 150 mm
• Abrasive grit: P40 (coarse)
• Backing type: pressure-sensitive self-adhesive
• Pack quantity: 100 discs
• Abrasive type: durable mineral grain for aggressive cutting

How to use

Ensure the sanding pad or platen surface is clean and free of dust or residues before applying a disc. Peel the protective liner from the adhesive backing and align the disc with the pad, pressing evenly from the centre outward to avoid air pockets. Operate the orbital sander at the manufacturer’s recommended speed for coarse sanding and apply moderate, even pressure; avoid excessive force that could reduce disc life or cause uneven wear. Replace the disc when the abrasive cutting performance declines.

Usage recommendations

For optimal results use on dry, stable surfaces and select P40 for aggressive stock removal; follow the sander manufacturer’s safety instructions, wear appropriate personal protective equipment (dust mask, eye protection and hearing protection), and use dust extraction where available to extend disc life and maintain a cleaner workspace.
